No, this is **absolutely false**!

I'm British, and my wife is Colombian. We've travelled separately and together to all these countries - Colombians *themselves* can get visas no problem! 

Some specific examples

* I've flown to the US directly from Colombia several times, and entered on the ESTA visa waiver
* We lived in Germany for two years, flying several times directly to and from Colombia. 
* We now live in the UK, same story
* My wife flew to Canada last year, just needing a standard tourist visa

By the way, enjoy Colombia, it's ***incredible***!
